US3760069A - Process for producing ferrous sulfate - Google

What is claimed is: 1. A process for producing ferrous sulfate monohydrate directly from iron in the absence of the production of the intermediate ferrous sulfate heptahydrate, the steps of said process comprising: a. admixing in a reaction zone quantites of iron and sulfuric acid, the sulfuric acid concentration being about 40 percent

Iron(II) sulfate - Wikipedia

Plant growth Iron (II) sulfate is sold as ferrous sulfate, a soil amendment [23] for lowering the pH of a high alkaline soil so that plants can access the soil's nutrients. [24] In horticulture it is used for treating iron chlorosis. [25] Although not as rapid-acting as ferric EDTA, its effects are longer-lasting.

Correction of Fe deficiency depends on individual crop response and many other factors. For instance, for vegetables, the rate is usually 0.4¨C1 lb. chelated Fe in 100 gal. of water per acre. Deciduous fruits need 0.1¨C0.2 lb. chelated Fe in 25 gal. of water per acre (Table 5). Foliar application is more effective than soil application.

ferrous sulfate manufacturing techniques & the affinity process

Ferrous Sulfate Manufacturing Techniques & The Affinity Process

Chemical Processing. There are several methods through which ferrous sulfate can be produced: Being prepared commercially by the action of sulfuric acid on iron (1). This is the chemical reaction: Fe + H 2 SO 4 -> FeSO 4 + H 2. To clarify in plain English: combining iron with sulfuric acid creates a reaction to form ferrous sulfate and hydrogen

Iron recovery from the coarse fraction of basic oxygen

In this study, a new reuse process of the coarse fraction of basic oxygen furnace (BOF) sludge based on iron recovery by the ferrous sulfate production was proposed. This study was based on three main steps: (i) characterization of the steel waste, (ii) evaluation and optimization of the recycling process, and (iii) characterization of ferrous sulfate produced. Acid leaching was used to
